Hi,
I have a 2006 VN2000 Classic LT with about 10,000 miles on it. Bought it new. I have never been on a long ride but have been doing constant modifications to the bike and have been to the dyno shop a few times. It has a Power Commander III USB, Cobra speedster longs with baffles out and Big sucker air kit. I have had several different types of air kits and have taken out the secondary throttle plates. I did strip the rear spark plug hole about 2 years ago, but re-tapped the hole (it was only about 4 threads that were bad), vacuumed out the cylinder hole and put in new spark plugs. Here is the problem. About 4 years ago I had 106 hp/ and 134 ft pounds tq to the wheel. Now I am at 102 hp with 126 pounds of tq to the wheel. The horsepower had even gone down to about 98 at one point. I don't ride very far with the bike and never rev the engine. Low rpm riding mostly (I wonder if that could be it)
I am currently running velocity stacks I made (3.75" long bell type) and that helped on the dyno, but the power is no where near what it used to be. The bike sort of lugs along like a Harley Road King (no offense to Harley riders). Doesn't have that incredible power anymore. Is there a possibility that I have lost compression with only 10,000 miles and a few dyno tunes? I did take the bike to 120 mph a few times. People also say they can smell my exhaust pretty bad. The bike has been dynode a few days ago with the velocity stacks(they have triple screens) The bike wasn't running too off before, but the horsepower/torque is still low. Any ideas??? I use Shell 89 octane and have used Sea foam twice also in the oil before an oil change. I use full synthetic oil as well. The bike is well maintained, but something is robbing it of power. I use a Ballistic Lithium battery which isn't actually all that great either. Doesn't start well. Starts bad in the cold......
Thanks for any input!
